The January/February dry spell took its toll on our snowpack, especially on the shady mid and upper elevation slopes. Snow on 2/16 & 2/17 preserved the weak layer, and snow on 2/22 through 2/25 started building the slab. Currently, in the Provo area, we have roughly 6-8" of settled snow above a very loose and faceted weak layer. This new snow above the weak layer is all of February's snowfall.
I don't think the 6-8" of new snow that sits above this weak layer is much of an issue now (unless you're on a wind-loaded slope). The bad news is the 6-8 inches of new snow buried and preserved this weak layer. The even worse news is once we get a large enough load, we will see a significant avalanche cycle on this layer. However, that will all depend on snow and water amounts in March. For now, it seems there is not enough weight on top of this layer to be much of a concern (see pic 2).
